Description

The invention relates to a household appliance device having a body and a closing element movably arranged therebetween between a closed position and an open position and with a line arranged both on the body and on the closure element.

Such a household appliance device may in particular be part of a refrigeration appliance. In refrigerators, in particular domestic refrigerators such as refrigerators, freezers or fridge-freezer combinations, the closure element can have an operating unit and / or display unit for controlling functions and displaying operating states of the refrigeration appliance. It is also conceivable that the closure element has an ice dispenser and / or a water dispenser. In such cases, there is a need to guide an electrical conduit or water conduit from the body into the closure member.

From the DE 10 2008 026 709 A1 an arrangement for guiding a cable from a body of a furniture element or device to a closure element is known, wherein the arrangement has a housing in which a portion of the cable extends, so that this section is to be covered or protected.

The present invention has for its object to provide a household appliance device mentioned above, which allows a safe and durable guidance of the line between the body and the closure element.

The object is achieved in that the household appliance device comprises a spring element which exerts a tensile stress at least on a line section of the line in at least the open position of the closure element.

The tension acts as a restoring force on the line section. The line section thus has in the open position of the closure element the Endeavor to return to its original state. This tension thus makes it possible to provide a sufficient length of the line without the risk that portions of the line assume an undesirable or uncontrolled shape, for example sagging.

The closure element may be formed by a door, a flap or a drawer front. In the open position, an interior region of the body, for example a storage space for goods to be cooled or frozen, becomes partially or completely accessible to a user, depending on the opening angle. The closure element may have an inner wall facing the body in the closed position and an outer wall facing away from the body. The inner wall and the outer wall may define a cavity filled with thermal insulation material.

The line can be formed for example by an electrical line, a data line or by a water pipe. It is also possible that the line within an outer sheath comprises both one or more electrical line (s) and / or data lines and / or one or more water line (s).

Embodiments of the invention are indicated in the dependent claims.

According to one embodiment, it is provided that the spring element exerts a tensile stress on the line section in the closed position of the closure element. The line section is thus under a tensile stress both in the open position and in the closed position. In this case, even in the closed position of the closure element, it can be ensured that the line section does not assume an undesired shape, in particular does not sag. This results in a precise and thus secure guidance of the line between the body and the closure element. In principle, it would be conceivable that the tensile force exerted on the line section in the closed state and the opened state of the closure element is (substantially) the same. However, according to one embodiment, a simple embodiment is achieved in that the tensile stress of the conduit section in the open position of the closure element is greater than the tensile stress of the conduit section in the closed position of Closure element. In particular, it can be provided that the tensile stress increases continuously when opening the closure element up to a maximum open position of the closure element, for example linearly with respect to an opening angle.

According to one embodiment, it is provided that the tensile stress of the conduit section in the open position of the closure element is produced by an elastic deformation of the conduit section. Although it can be provided in this embodiment, a respect to the line separate, additional spring mechanism. In principle, however, it can be provided that the entire tensile stress exerted on the line section is generated exclusively by the elastic deformation of the line section itself. This results in a simple yet effective solution to the problem. The elastic deformation could be done by stretching the line section along its longitudinal axis. Such an embodiment would be conceivable in particular for a water pipe, which consists essentially only of an elastic cable jacket. According to one embodiment, however, it is provided that the spring element is formed by formed in the line section spring portions. This embodiment can be used, for example, for electrical lines and data lines. In particular, this embodiment enables elastic deformation of the conduit section without stretching the same along its longitudinal axis. The spring sections can in particular be designed such that the elastic deformation, preferably exclusively, is produced by a bending deformation. According to one embodiment, it is provided that the spring sections are formed by a helical shape or helical shape of the line section. It is possible that the complete line, if appropriate with the exception of the two end sections of the line, has a helical shape. The generation of the tensile stress by the elastic deformation of the line section takes place by increasing the pitch of the helix or the pitch of the helix.

Additionally or alternatively, according to one embodiment, it may be provided that the spring element is formed by a separate spring mechanism with respect to the line. A separate spring mechanism allows application-specific and precisely adjustable tension. Although it would be conceivable in principle, a multi-part Spring mechanism partially on or within the body and to be arranged on or within the closure element. In order to achieve a compact construction, however, it can be provided to arrange the spring mechanism exclusively on or within the body or on or inside the closure element.

According to one embodiment, it is provided that the spring mechanism comprises a member for rolling up a portion of the pipe section. In particular, it may be provided that the length of a portion rolled up onto the element in the closed position of the closure element is greater than the length of a section rolled up onto the element in the open position of the closure element. According to one embodiment, it is provided that the element is formed by a rotatably arranged on the body or on the closure element and can be tensioned by a spring roller. An axis of rotation of the roller can be arranged in a stationary manner relative to that structural unit of the body and closure element on which the roller is arranged. The role can be tensioned by a torsion spring.

According to one embodiment, it is provided that the spring mechanism forms a section of the line section in the closed position of the closure element by means of a force generated by a spring to a curved portion. The curved portion may in particular form a loop or a bow. In this case, the spring mechanism can directly form or deflect the curved section by means of the spring. To minimize frictional resistance, however, it may be provided that the spring mechanism has a guide element, which forms the curved portion. The guide element may in particular have a guide groove. The curved portion can be guided with play in the guide groove. The guide element may in particular be arranged stationary with respect to a resilient end portion of the spring. For example, the guide element may be formed by a guide cap mounted on a resilient end portion of the spring. However, it is also conceivable that the guide element is formed to further minimize the friction by a roller guide. Thus, according to one embodiment, the spring mechanism has a roller which is rotatably arranged on the body or on the closure element and which is displaceably arranged counter to the spring force generated by the spring. The roller may have a guide groove on its lateral surface.

According to one embodiment, it is provided that the spring mechanism is arranged completely on the closure element. The spring mechanism may in particular be arranged at an end portion of the closure element. For example, the spring mechanism may be disposed at an upper or lower end portion. This configuration allows a simple door stop change, since the spring mechanism is easily accessible and thus easily disassembled and again mirror-inverted mounted in the width direction

The home appliance device may include a cover member for partially or completely covering the spring mechanism. According to one embodiment, it is provided that the closure element has a fastening means for a, in particular plate-shaped, decorative element and a cover for partially or completely covering the fastening means and that the cover member covers the spring mechanism partially or completely.

According to one embodiment, it is provided that the household appliance device comprises a line deflection, in particular a deflection roller, which causes a change in direction of the guided over the line deflection line. The line deflection makes it possible to guide the line targeted to desired connection points on the body or the closure element. Preferably, the line deflection has a groove for guiding the line.

According to one embodiment, it is provided that the spring element can be tensioned or tensioned by a relative movement of the closure element relative to the body when the closure element is opened. In particular, it can be provided that the spring element can be tensioned or tensioned exclusively by this relative movement.

The body and the closure element can be connected to one another by one or more bearing elements, for example hinges or pull-out rails (telescopic rails). The one or more bearing elements allow an adjustment of the closure element between the closed position of the open position. The body and the closure element can in particular by means of one, by means of two or be interconnected by means of several multi-joint hinges. A multi-joint hinge is characterized in that it allows both a rotation and a translational movement between the body and the closure element.

According to one embodiment, it is provided that the line is fastened by means of a, in particular releasable, plug-in connection to the body and / or on the closure element. In this way, a simple to bewerkstelligender door stop change is possible.

According to one embodiment, it is provided that the household appliance device is a refrigeration device and preferably the closure element is a door. It is conceivable that the refrigeration device has two or more closure elements or doors and two or more lines are guided by the body according to the invention in the closure element or doors.

The household appliance device 2 comprises a body 3 and a pivotally arranged on the body by means of two bearing elements 4 closure element 5. The bearing elements 4 are each formed by multi-hinge hinges 6. The household refrigerator 1 is arranged in a furniture recess 12, which is shown transparent for illustrative purposes. If the closure element 5 from the in FIG. 1 shown, closed position is brought into an open position, this leads to the body 3 thus both a rotational movement and a translational movement. The closure element 5 is formed in this case by a door 7. Within the body 3 is an unillustrated storage space for receiving refrigerated goods, which is accessible through the door 7. Both the body 3 and the door 7 have cavities which are filled with thermal insulation material. The body 3 has as outer lining side walls 8, a cover element 9, a bottom element and a rear wall 10. Between this outer lining and an inner container, not shown, there is a cavity which is filled with the thermal insulation material. The door 7 has an outer wall 13 and an inner wall facing the storage space in the closed position of the door 7. Between the outer wall 13 and the inner wall is a cavity which is filled with the thermal insulation material. The door 7 has a fastening means 15 for fastening a plate-like decorative element, for example a furniture panel. Those portions of the fastening means 15, which are arranged on a narrow side 11 of the door 7, but a cover 16 are substantially covered. Between the body 3 and the door 7, a conduit 17 extends. The conduit 17 is fastened both to the body 3 and to the door 7. The line 17 emerges from a forwardly facing front side of the body 3 and occurs on the upper narrow side 11 of the door 7 below the cover 16 in the door 7 a.

Fig. 2 shows a section of a front view of the household refrigerator Fig. 1 , the upper portion, wherein for illustration purposes, the cover member 16 is shown transparently. In this embodiment, the spring element 18 is formed by a line section 17 'of the line 17, in particular by the shape of the line 17. The line 17 has a helical shape or helical shape. The individual helix form spring sections 19. In this embodiment, the helical shape or helical form extends over the entire line 17, ie, the line section 17 'substantially corresponds to the entire line 17. In the open position of the door 7, the line 17 is stretched relative to the closed position of the door 7, so the slope of the helix or helix increases and the line 17 has a tensile stress. The line 17 has at both end portions plug elements 20, with which the line 17 is releasably secured on the one hand on the upper narrow side 11 of the door 7 and on the other hand on an end face of the body 3.

Fig. 3 shows sections of a second embodiment. Fig. 3a shows an upper section of a front view of a household refrigerator 1 according to the invention, wherein the door 7 is in the closed position. Fig. 3b shows a perspective view of the door 7 in the open position. In both illustrations, the cover 16 is shown transparent for illustrative purposes. The spring element 18 is formed by a spring mechanism 21. The spring mechanism 21 comprises a roller 22, which is tensioned by a (not shown) spring. A portion 17 "of the conduit portion 17 'is rolled up on the roller 22. The roller 22 is rotatably fixed to the door 7, with an axis of rotation of the roller 22 being fixedly arranged with respect to the door 7. In FIG Fig. 3a When the door 7, in particular when the door 7 is moved in translation relative to the body 3, these windings begin to unwind against the force caused by the spring, so that At least in the open position of the door 7, a tensile stress acts on the line section 17 '(to the right of the spring mechanism 21) When the door 7 is closed, the tension causes the line 17 to partially re-engage the roller 22 is wound up.

Fig. 4 shows sections of a third embodiment with too Fig. 3 comparable views. The spring element 18 is in turn formed by a spring mechanism 21. The spring mechanism 21 comprises two springs 23, namely coil springs.

Each spring 23 has a stationary relative to the door 7 end portion 23a and a resilient, ie free, end portion 23b. The stationary end portions 23a are fixed to the cover 16 in this embodiment. At the resilient end portions 23b, a guide member 24 is arranged in each case. Each guide member 24 has a groove in which portions 17 "" of the conduit portion 17 'is received. The grooves are dimensioned such that the portions 17 "" can slide through the grooves with little friction. In the in Fig. 4a shown closed position of the door 7, the portions 17 "" formed by means of the springs 23 forces to curved sections. The line section 17 'thus has a tensile stress. When opening the door 7, in particular if it performs a translational movement relative to the body 3, the springs 23 are compressed. If the door 7 from the in Fig. 4b As shown in the open position shown, the spring force of the springs 33 ensures that the sections 17 "" are again formed into curved sections.

Fig. 5 shows sections of a fourth embodiment with too Fig. 3 comparable views while in Fig. 6 a perspective section of this embodiment is shown. The spring element 18 is in turn formed by a spring mechanism 21. The spring mechanism 21 comprises a spring 23, in the form of a helical spring, with a stationary end 23a and a resilient end 23b. The fixed end 23 a is fixed to an abutment 25 on the door 7. The spring mechanism 21 further comprises a roller 26 and a roller bearing 27, within which the roller 26 is rotatably mounted. The roller bearing 27 is arranged displaceably against a force generated by the spring 23. For this purpose, a guide carriage 28 is arranged on the roller bearing 27, which can move within a slide guide 29. The resilient end 23b of the spring 23 contacts the guide carriage 28. As soon as the door leaves the in Fig. 5a shown closed position, the guide carriage 28 begins against the force generated by the spring 23 to compress them ie the guide carriage 28 moves along the carriage guide 29 to the right. The line section 17 'rolls over the roller 26. At least in the in Fig. 5b shown open position of the door, the spring 23 is compressed, so that acts on the line section 17 ', a tensile stress. As in particular in Fig. 6 can be seen, the household refrigerator 1 further comprises a line deflection 30. This serves a change of direction over the Conduction lead 30 guided line 17 so that the line 17 is guided in the desired direction in the spring mechanism 21.

Fig. 7 shows a section of a fifth embodiment with a to Fig. 3a comparable view, that is, in a closed position of the door 7. In contrast to the fourth embodiment, a further line deflection 30 is arranged on the door 7. The conduit deflection 30 is formed by a roller, whose lateral surface has a groove to guide the conduit 17. This line deflection 30 makes it possible to guide the line 17 in a widthwise central portion of the door 7. The line 17 can thus enter centrally in the door 7 substantially in the width direction X, so that a Türanschlagwechsel can easily be done without the connection of the line 17 with the door 7, a plug connection would be necessary. <B> LIST OF REFERENCES </ b> 1 Household refrigerator 21 spring mechanism 2 Appliances device 22 role 3 corpus 23 feather 4 bearing element 23a fixed end section 5 closure element 23b resilient end section 6 Multilink hinge 24 guide element 7 door 25 abutment 8th Side wall 26 role 9 cover element 27 roller bearing 10 rear wall 28 guide carriage 11 narrow side 29 carriage guide 12 furniture niche 30 line deflection 13 outer wall 15 fastener 16 cover 17 management 17 ' line section 17 " section 17 '' section 17 "" section 18 spring element 19 spring section 20 male member
